aa_getprocattr_raw, aa_getprocattr − read and parse procattr data
aa_getcon, aa_gettaskcon − get task confinement information
aa_getpeercon − get the confinement of a socket’s other end (peer)
int aa_getprocattr_raw(pid_t tid, const char *attr, char *buf, int len,
int aa_getprocattr(pid_t tid, const char *attr, char **buf, char **mode);
int aa_gettaskcon(pid_t target, char **con, char **mode);
int aa_getcon(char **con, char **mode);
int aa_getpeercon(int fd, char **con);
Link with −lapparmor when compiling.
The aa_getcon function gets the current AppArmor confinement context for the current task. The confinement context is usually just the name of the AppArmor profile restricting the task, but it may include the profile namespace or in some cases a set of profile names (known as a stack of profiles). The returned string *con should be freed using <free()>.
The aa_gettaskcon function is like the aa_getcon function except it will work for any arbitrary task in the system.
The aa_getpeercon function is similar to that of aa_gettaskcon except that it returns the confinement information for task on the other end of a socket connection.
The aa_getprocattr function is the backend for the aa_getcon and aa_gettaskcon functions and handles the reading and parsing of the confinement data from different arbitrary attr files and returns the processed results in an allocated buffer.
The aa_getprocattr_raw() is the backend for the aa_getprocattr function and does not handle buffer allocation.
On success zero is returned. On error, −1 is returned, and errno(3) is set appropriately.
The apparmor kernel module is not loaded or the communication via the /proc/*/attr/file did not conform to protocol.
Insufficient kernel memory was available.
Access to the specified file/task was denied.
The specified file/task does not exist or is not visible.
The confinement data is to large to fit in the supplied buffer.
